This guide book covers exclusively pyralids in the Pyralidae family which span the subfamilies Pyralinae, Epipaschiinae, Galleriinae and Phycitinae. Each species is given an exact description along with useful information on its biology. Moths of Europe, Volume 4 features 69 colour plates illustrating 650 species in 1320 photos. 200 line drawings show clearly certain anatomical characters, in particular the genitalia of taxa that are difficult to distinguish just by their external aspects. Distribution maps are provided for most of the species covered.
